Hi together,
Currently I am planning a storage network for making backups of several
servers. At the moment there are several dedicated backup server for it: 4
nodes; each node is providing 2.5 TB disk space and exporting it with CIFS over
Ethernet/1 GBIT. Unfortunately this is not a very flexib

You will need to have redundancy somewhere to avoid possible data
loss. If redundancy is in the backend, then you should be protecte
This is basically the setup I suggested a year or so ago. While the theory is
sound, the major problem with it is that iSCSI and ZFS are not a great
combination when a device (in your case server) goes down. If you create a
pool of several iSCSI devices, when any one fails, the entire pool wil
That is very interesting. What kind of hardware did you use? Do you have any
statistics about throughput and I/O behavior? Maybe you could provide the
detailed architecture. Unfortunately I did not find your e-mail address in your
user profile for direct contact.

Bob, thank you very much for your detailed answer. Indeed, Resilvering could be
a very difficult situation in such a big storage pool. I could solve this issue
by building a pool for each backend node. But then I run into the same problems

Dave, what kind of hardware did you used? I am scared about the bandwith and
I/O throughput of the zfs gateway.

I don't have any statistics myself, but if you search the forum for iscsi,
there was a long thread a few months back with some performance figures. I
didn't really do that much testing myself, once I hit the iscsi bug there
wasn't any point doing much more.
There has been some work on that rec
You might want to look into the products from a company called
DataCore Software, http://datacore.com/products/prod_home.asp. I've
used them and they are great stuff. They make very high performing
iSCSI and FC storage controllers out of leveraging commodity hardware,
